I have wanted this too. Until recently, I did not understand a
user-contributed patch is called for in a case like this.   

I propose to do this way, to be more easily usable from the java side
(i.e., no more selector needed).  I want to require that the class
supplying the data have a method like this

- getDataKey: (int) x
{
        imagine a case statement here that gives back whatever data corresponds
with x.  This is, of course, context specific.
}

And then the EZGraph will have a new method, 

- (id <EZSequence>)createSequence: (const char *)aName withFeedFrom:
anObj andDataKey: (int) x;

 
One might guess this would be easy, but as I look at the Swarm source
code, it is not trivial. EZGraph is IMHO somewhat tricky because it is
designed to allow the passing around of selectors (which Java doesn't
allow) and it creates some questions for me to work out.  Nevertheless,
I think I can get it.
